Expert's answer
We suggest you consider the problem of soil contamination by lead:
Lead is a heavy, soft, malleable metal. Due to its physical and chemical properties, industry has found countless uses for lead in our daily lives. While certain uses of lead are banned, lead is still found in a myriad of products. Important sources of lead in the environment today include:
• Lead paint, and resulting lead dust, found in and around homes built before 1978 (lead-based paint was banned in 1978). Lead dust from deteriorated lead-based paint is the most significant contributor to childhood lead poisoning.
• Lead from automobile emissions (before leaded gasoline was finally banned in 1986) that has been deposited on land and surface water.
• Lead in occupational settings (often brought home on clothes or skin).
• Lead from industrial emissions, such as lead smelters, lead mining, hazardous waste sites, and battery-recycling plants.
• Lead in drinking water caused by lead-containing plumbing.
• Lead-containing tableware, such as leaded-crystal glassware and lead-glazed pottery.
• Certain hobbies and activities that use lead (e.g., car radiator repair, target shooting, stained glass making, glass or metal soldering).
• Certain folk remedies that contain lead (e.g., azarcon, greta).
