Effects of DDT have been seen in many organisms including birds and humans. The effects seen in humans is quite minimal to that of insects and birds. DDT causes lost of many insects and young birds. In humans, it causes vomiting, seizures etc.
2. Lead: it enters the biosphere by absorption and consumption means. Humans through the use of lead paint, smoking of cigarettes, use of cosmetics and combustion of coal accumulates lead in their bodies. Lead can't be synthesize by human, therefore it accumulates and biomagnify within their systems.
The effects of lead in human include; vomiting, stroke and abdominal pains. In tough scenario, it causes immune system deterioration and cardiovascular diseases.
