Sunscreen pollution refers to the environmental impact of sunscreen products on marine ecosystems. It is caused by the presence of UV filters and other chemical compounds in sunscreens that are not efficiently removed during the wastewater treatment process and end up in oceans and other aquatic environments. These pollutants have been detected in various parts of the world, including marine ecosystems, agricultural practices, and even in bird eggs and bird life. The impact of sunscreen pollution on marine life, including coral reefs, fish, and other organisms, has been a growing concern, with studies indicating that certain ingredients in chemical and physical sunscreens can cause bleaching, deformities, and a decrease in fertility. The global sunscreen market is expected to grow, highlighting the urgency of addressing this issue through comprehensive studies and the development of environmentally friendly alternatives.

What You'll Learn
Sunscreen chemicals are toxic to marine life
Sunscreen pollution is a pressing issue that has serious impacts on marine life and ecosystems. The chemicals found in sunscreen products, designed to protect our skin from harmful UV rays, are proving to be detrimental to the health of marine organisms.
Sunscreen products contain UV filters, which are organic and inorganic compounds that absorb UV radiation. These filters are necessary to enhance the performance and appearance of sunscreens. However, these same filters are toxic to marine life when they enter waterways. The indirect transfer of these UV filters to marine ecosystems occurs through wastewater systems. Activities such as showering, swimming, and washing clothes allow sunscreen residue to enter wastewater treatment plants, and eventually, marine environments.
The effects of these chemicals on marine life are extensive and far-reaching. Organic UV filters, for example, tend to bioaccumulate in aquatic animals due to their solubility in fatty solvents. This phenomenon, known as biomagnification, illustrates how these pollutants accumulate in the food chain. In addition, exposure to these chemicals impacts the basic functions of animal life, including survival, development, and reproduction.
Coral reefs, one of the most valuable ecosystems on Earth, are particularly vulnerable to sunscreen pollution. Chemicals found in sunscreens, such as oxybenzone, octinoxate, and avobenzone, have been shown to induce bleaching, damage DNA, deform young corals, and even lead to mortality. Moreover, sunscreen pollution impairs the growth of green algae, which is an essential part of the marine food web. The consequences of this disruption can be seen throughout the food chain, even affecting species like the Hawaiian green sea turtle.
To address this issue, individuals can opt for sunscreen products that do not contain harmful chemicals. Mineral-based sunscreens, which use minerals like zinc oxide and titanium dioxide to block UV rays, are considered reef-friendly and have less impact on aquatic life. Additionally, wearing UV-protective clothing, such as sun shirts and pants, is a recommended alternative to chemical sunscreens. By making conscious choices, we can protect both our skin and the delicate balance of marine ecosystems.

UV filters are pseudo-persistent pollutants
Organic UV filters are compounds that absorb UV irradiation due to their highly conjugated structure. They are used in sunscreens, cosmetics, and industrial products to prevent ultraviolet radiation damage. They are also used as antioxidants in plastics, paints, and photo-initiators to prevent material aging.
The massive production and usage of these organic UV filters have resulted in their extensive release into the aquatic environment, making them an important group of emerging contaminants. They have been detected in various environmental matrices worldwide, including water, sediment, soil, and even indoor dust. The concentration of UV filters in the water depends on several factors, such as the area, date, and time of sampling, and whether swimmers are present.
Organic UV filters have been found to bioaccumulate in aquatic organisms, impacting their survival, development, and reproduction. They have also been detected in birds, illustrating the severity of biomagnification. Humans are also widely exposed to these pollutants through multiple pathways, and there are concerns about their potential long-term health effects.
Regulatory limits have been set, but organic UV filters still enter the environment through direct wash-off during swimming, evaporation, leaching from products, and incomplete removal in wastewater treatment plants. Once in the environment, they can undergo phototransformation and biotransformation, forming transformation products that pose health risks to humans and wildlife.
In conclusion, organic UV filters are pseudo-persistent pollutants that have widespread environmental and health impacts. Their extensive usage and continuous release into the environment have triggered concerns about their persistence and toxicity.

Inorganic UV agents use surface coating
Sunscreen pollution has been found to have detrimental effects on marine ecosystems. It has been reported that an increase in tourism in coastal areas is correlated with an increase in UV agents in the waters of these areas. UV filters are present in sunscreen, moisturisers, shampoos, and makeup products, and these products can enter marine ecosystems through wastewater systems.
Inorganic UV agents are incorporated into sunscreen products through the use of surface coating. UV coatings are surface treatments that protect the underlying material from ultraviolet radiation. UV-curable coatings can be used to impart a variety of properties to polymeric surfaces, including glare reduction, wear or scratch resistance, anti-fogging, microbial resistance, and chemical resistance.
UV-induced polymer photodegradation can be inhibited or delayed by introducing stabilizers into the polymer matrix or into a coating applied to the surface. The effectiveness of UV blockers/absorbers is greatest when they are concentrated on the surface, as in an applied coating or film on the polymeric component. Carbon black, for instance, absorbs strongly in the UV and visible regions.
Inorganic UV layers like aluminium oxide Al2O3, aluminium hydroxide Al(OH)2, and hydrated silica SiO2 are chosen to passivate the TiO2 surface. The level of UV protection provided by inorganic fillers increases as the size of the particles decreases.
UV curable organic/inorganic hybrid coatings are environmentally friendly paint products that have been rapidly developing in recent years. The properties of hybrid coatings can be enhanced by the inorganic incorporation into the organic matrix, improving characteristics such as abrasive resistance, heat resistance, corrosion resistance, and chemical stability.

Organic UV filters bioaccumulate in aquatic animals
Sunscreen use has increased in recent years as sunscreen products minimize the damaging effects of solar radiation. However, sunscreen pollution can have major impacts on aquatic ecosystems, including corals, fish, mammals, algae, and even entire food webs.
Organic UV filters are compounds that absorb UV irradiation due to their highly conjugated structure. They are highly lipophilic, meaning they tend to accumulate in fatty tissues. This is because they have a high octanol/water partition coefficient (Kow), which indicates the relationship between the fat and water solubility of a substance. If the Kow value is greater than 1, the substance is easily soluble in fatty solvents, whereas if it is lower than 1, it is considered soluble in water.
Organic UV filters tend to bioaccumulate in biota, and this has been reported in various aquatic animals, including corals, algae, arthropods, mollusks, echinoderms, marine vertebrates, and even Swiss cormorants and bird eggs in Spain. These filters enter the environment mainly through aquatic pathways, such as swimming and bathing, as they can be washed off the skin and enter waterways. They are also transferred indirectly through wastewater systems, as showering, urinating, and washing clothes allow sunscreen residue to end up in waters, which may later be transferred to marine ecosystems.
The bioaccumulation of organic UV filters can have adverse effects on aquatic organisms, including endocrine disruption, reduced fertility and reproduction, and developmental issues. These effects can be amplified through the food chain, with contaminants detected in predators such as sharks, turtles, and dolphins, which travel large distances and connect different ecosystems, contributing to biomagnification.

Coral reefs are threatened by sunscreen chemicals
Coral reefs are one of the most valuable ecosystems on Earth, providing billions of dollars in economic and environmental services, such as food, coastal protection, and tourism. However, they face serious threats from climate change, unsustainable fishing, land-based pollution, coastal development, disease, and invasive species. In addition to these threats, scientists have discovered that some of the chemicals found in sunscreen and other personal health products also harm coral reefs.
Sunscreen pollution can have major impacts on coral reefs, fish, mammals, and the whole ecosystem. It can cause coral bleaching, DNA damage, deformities in young corals, and even coral death. Certain chemical UV filters found in sunscreen, such as oxybenzone, octinoxate, avobenzone, benzophenone-1, Benzophenone-8, OD-PABA, 4-Methylbenzylidene camphor, 3-Benzylidene camphor, and nano-Titanium dioxide, have been identified as harmful to corals. These chemicals can accumulate in the tissues of corals and other marine organisms, leading to detrimental effects.
The issue of sunscreen pollution in coral reefs is exacerbated by the increasing popularity of coastal areas for tourism and recreational activities. The influx of tourists and swimmers in these areas correlates with higher concentrations of UV agents in the waters. When swimmers enter the ocean, river, or lakes, the sunscreen they have applied washes off into the water. It is estimated that approximately 14,000 tons of sunscreen enters waterways globally each year, with significant amounts accumulating in shallow areas popular with swimmers.
To address this issue, individuals can take steps to choose reef-safe sunscreen products. While some brands label their products as "reef-safe" or "reef-friendly," it is important to scrutinize the active ingredients. Ingredients such as oxybenzone, octinoxate, and avobenzone should be avoided as they are known to be harmful to marine life. Instead, individuals can opt for mineral-based or physical sunscreens that use minerals like zinc oxide and titanium dioxide to block harmful rays from the sun. These sunscreens are biodegradable and free from harmful chemicals, providing a safer alternative for both skin and marine life.
Additionally, individuals can protect themselves and the reefs by seeking shade between 10 am and 2 pm, wearing UV-protective clothing like sun shirts and pants, and using Ultraviolet Protection Factor (UPF) sunwear. By making these simple choices, we can play a part in safeguarding coral reefs and the marine ecosystem.
