Statement I: The excessive level of pesticide residues in fruits, milk, eggs and vegetables are responsible for diseases like cancer, sterility even deaths.
Statement II: Polychlorinated biphenyl is a best example.
Analysis of Statement I: Pesticide Residues and Health Risks
Statement I claims that excessive levels of pesticide residues in common food items like fruits, milk, eggs, and vegetables are harmful and can lead to serious health problems, including diseases such as cancer, sterility, and even death. This statement is generally considered correct.
- Pesticide Residues: Pesticides are substances used to kill pests. When used on crops or livestock, small amounts can remain on or in the food products.
- Health Impacts: Regulatory bodies set limits for these residues. However, excessive exposure, either through consuming contaminated food over time or consuming food with levels significantly above safety limits, has been linked by scientific research to various adverse health effects. These can range from short-term illnesses to long-term chronic conditions like endocrine disruption, neurological problems, reproductive issues (sterility), and increased cancer risk.
- Severity: The severity of the impact depends on the type of pesticide, the level of exposure, and individual susceptibility. In extreme cases, high-level poisoning can indeed be fatal.
Analysis of Statement II: Polychlorinated Biphenyls as an Example
Statement II suggests that Polychlorinated biphenyl (PCB) is a prime example related to the issue raised in Statement I. This statement is incorrect in the context of pesticide residues.
- What are PCBs?: Polychlorinated biphenyls (PCBs) are a group of manufactured organic chemicals. They were widely used in industrial applications such as coolants, insulating fluids in transformers, plasticizers, and in carbonless copy paper, primarily before they were banned in the 1970s in many countries due to their environmental persistence and toxicity.
- PCBs vs. Pesticides: While PCBs are known environmental pollutants and can cause serious health problems (including cancer and immune system issues), they are not classified as pesticides. Pesticides are specifically designed to target and kill pests (insects, weeds, rodents, etc.), whereas PCBs were industrial chemicals.
- Misclassification: Therefore, referring to PCBs as a "best example" specifically for *pesticide residues* is inaccurate. While both are harmful contaminants found in the environment and food chain, their origin and classification differ.
Conclusion
Based on the analysis, Statement I accurately describes the dangers associated with excessive pesticide residues in food. Statement II incorrectly identifies Polychlorinated biphenyls as a relevant example in the context of pesticide residues, as PCBs are industrial chemicals, not pesticides.
Important Questions from Statement and Conclusion (Notes)
