Question

State the impact of soil pollution on agricultural production.​

Answer 1

Answer:

Explanation:

Many common soil pollutants are carcinogenic causing humans who are exposed to these pollutants to be far more likely to develop cancer than those who are not. For example, regular exposure to benzene is known to cause leukemia in both children and adults and exposure to polychlorinated biphenyls (PCBs) is linked to liver cancer. Soil pollution can also cause neuromuscular blockage as well as depression of the central nervous system, headaches, nausea, fatigue, eye irritation and skin rash.  Soil does not need to be highly contaminated to be harmful to humans. Soil that is not significantly polluted may still harm humans directly though bioaccumulation, which according to Pollution Issues, occurs when plants are grown in lightly polluted soil, which continuously absorb molecules of the pollutants. Since the plants cannot get rid of these molecules, they accumulate in the plant, causing higher amounts of pollution to exist in the plant than in the soil. Animals who eat many of these polluted plants take on all the pollution those plants have accumulated. Larger animals who eat the plant-eating animals take on all the pollution from the animals they eat. Humans who eat plants or animals that have accumulated large amounts of soil pollutants may be poisoned, even if the soil itself does not contain enough pollution to harm human health. Furthermore, the presence of heavy metals in soil in toxic amounts can cause irreversible developmental damage in children. Lead and mercury in soil may also be harmful to human health. Although lead and mercury may be found naturally in soil, high concentrations of either metal may cause damage to the developing brains of young children, which in turn may lead to neurological problems. Humans of any age may also suffer kidney or liver damage from exposure to excessive mercury in soil. In addition to endangering human health, soil pollution can also cause economic damage. For example, in some parts of China, soil that is polluted with heavy metals is nevertheless used to grow grain. The grain grown in these soils is often polluted with heavy metals. According to China Dialogue, an estimated 12 million tons of polluted grain must be disposed of each year, costing Chinese farmers up to 20 billion yuan, or about $2.57 billion U.S.
