Water Pollution's Impact On Pakistan's Biodiversity

Water pollution is a major threat to public health in Pakistan, where drinking water quality is poorly managed and monitored. Both surface and groundwater sources are contaminated with coliforms, toxic metals, and pesticides throughout the country. This is due to human activities such as the improper disposal of municipal and industrial effluents and the indiscriminate application of agrochemicals in agriculture.

The Indus River, the primary water source for over 180 million people in Pakistan, is also affected by pollution. The river receives untreated sewage and industrial waste, including organic matter, ions, and inorganic waste. This has led to a reduction in fish species diversity and a decrease in the supply of subsistence food for those living near the river.

Water pollution in Pakistan has severe health implications for both humans and other living things. It is estimated that water-related diseases cause an annual national income loss of 25-58 billion Pakistani rupees and that over 250,000 children die each year from diarrheal diseases alone. Waterborne diseases account for 80% of all diseases in the country and one-third of all deaths.

The impact of water pollution extends beyond human health. For example, the Indus River's water flow is threatened by regional environmental changes and rising tensions between India and Pakistan, which share the river. This could lead to a military conflict that would endanger the lives and security of millions.

To address water pollution in Pakistan, urgent steps are needed to improve water quality and protect public health. This includes proper filtration and disinfection of public water, separating water supply and sewerage pipe networks, and enforcing environmental laws.

Water pollution is a major threat to public health in Pakistan, with drinking water quality poorly managed and monitored

Water pollution is a significant threat to public health in Pakistan, with drinking water quality poorly managed and monitored. The country ranks 80th out of 122 countries for drinking water quality, with both surface and groundwater sources contaminated with coliforms, toxic metals, and pesticides. This has led to various drinking water quality parameters set by the World Health Organization being frequently violated. The main factors contributing to the deterioration of water quality are human activities such as the improper disposal of municipal and industrial effluents and the indiscriminate application of agrochemicals in agriculture. These microbial and chemical pollutants are responsible for various public health problems, including waterborne diseases.

Pakistan's water resources are under immense stress due to rapid population growth, urbanization, and unsustainable consumption of water in industry and agriculture. The country has essentially exhausted its available water resources and is facing critical water shortages and pollution. The water precipitation rate is lower than the evaporation rate, causing a continuous decrease in water quantity in rivers, lakes, and groundwater. This, coupled with increasing demand, has resulted in severe water shortages in almost all sectors of the country.

The poor quality of drinking water available to the public has forced people to rely on expensive alternatives like commercially available mineral water packed in plastic bottles. However, this water is also not completely safe due to a lack of proper monitoring of processing plants. As a result, the majority of the population is exposed to contaminated and polluted water, which may cause a multitude of water-related health problems.

The increasing pollution of drinking water sources and its consequent effects on human health and the environment is an issue of great concern in Pakistan. Various studies have been conducted to highlight the problem of water pollution, with a special emphasis on major pollutants, sources of pollution, and consequent health problems. The data presented in these reviews are extracted from various studies published in national and international journals, as well as reports released by the government and non-governmental organizations.

The impact of water pollution on public health in Pakistan is far-reaching. About 2.3 billion people worldwide suffer from water-related diseases, with more than 2.2 million people dying each year due to drinking unclean water and inadequate sanitation. In Pakistan, water-related infectious and parasitic diseases account for approximately 60% of infant mortality. The situation is even worse in drought-affected areas, where people have no access to fresh drinking water and are forced to consume brackish water.

To address the issue of water pollution and its impact on public health, Pakistan has implemented various environmental legislations, such as the Pakistan Environmental Protection Ordinance 1983, which led to the establishment of the Pakistan Environmental Protection Council and the Pakistan Environmental Protection Agency. However, the effectiveness of these legislations has been questioned due to slackness in their implementation.

Overall, water pollution is a critical issue in Pakistan, and it is essential to improve drinking water quality to protect public health. This requires proper management and monitoring of water resources, as well as addressing the main factors contributing to water pollution, such as improper disposal of effluents and the indiscriminate use of agrochemicals.

Water pollution in Pakistan is caused by human activities like the improper disposal of municipal and industrial effluents and the indiscriminate application of agrochemicals in agriculture

Water pollution in Pakistan is a pressing issue, largely caused by human activities such as the improper disposal of municipal and industrial effluents and the excessive use of agrochemicals in agriculture.

The inadequate management of the river flow has led to devastating floods, affecting millions and highlighting the urgency of effective water governance.

Water pollution in Pakistan is a critical issue that demands immediate attention and action. The country faces a dual challenge of water scarcity and contamination, threatening both its economy and the well-being of its citizens, particularly the most vulnerable populations.

Heavy metal contamination in water, soil, and vegetables poses serious health risks to the population

Water pollution is a significant threat to public health in Pakistan, where drinking water quality is poorly managed and monitored. Both surface and groundwater sources are contaminated with coliforms, toxic metals, and pesticides, with human activities such as improper disposal of industrial and municipal waste contributing to the deterioration of water quality.

Heavy metal contamination in water, soil, and vegetables is a pressing issue in Pakistan, posing serious health risks to the population. Trace heavy metals such as arsenic, cadmium, lead, chromium, nickel, and mercury are prevalent environmental pollutants, particularly in areas with high anthropogenic pressure. These metals can cause serious problems for all organisms, including humans, as they accumulate in the food chain.

In Pakistan, industrial effluents, municipal sewage, and agricultural wastes are discharged into rivers, worsening water pollution. Coastal areas in Karachi, for instance, receive huge quantities of industrial effluents and domestic sewage, which are released directly into the coastal environment. This, coupled with increasing population pressure, urbanization, and industrialization, poses a significant threat to the marine environment and human health.

The consumption of contaminated water and vegetables can lead to various health issues. Arsenic exposure, for example, has been linked to an elevated risk of developing skin cancer and cancers of the liver, lung, bladder, kidney, and colon. Cadmium intoxication can cause lung, renal, and skeletal damage, as well as itai-itai disease and cancer. Lead poisoning can affect both children's and adults' IQ, metabolism, and renal function, and in severe cases, lead to coma and death.

The presence of heavy metals in wastewater-irrigated vegetables has been documented in various studies. For instance, a study in Bhakkar, Pakistan, found that wastewater-irrigated vegetables had higher levels of heavy metals such as cadmium, lead, and nickel compared to vegetables irrigated with tube well water. Another study in the industrial cities of Sialkot and Wazirabad revealed that wastewater-irrigated soil and food crops exhibited high levels of cadmium, lead, chromium, manganese, and nickel.

The health risks associated with heavy metal contamination are significant, with the Health Risk Index (HRI) exceeding 1 for lead, cadmium, and manganese in certain vegetables. This indicates a potential health risk to the population, particularly in areas where wastewater is used for irrigation without proper treatment.

Overall, heavy metal contamination in water, soil, and vegetables in Pakistan poses a serious threat to human health, and measures are needed to mitigate these risks.
