They get into water bodies through domestic sewage and animal excreta. SaralStudy helps in prepare for NCERT CBSE solutions for Class 11th chemistry. Polynuclear hydrocarbons having fused benzene systems have carcinogenic properties. The fumes from tobacco, petroleum, and coal combustion usually contain polynuclear hydrocarbons. For your agricultural field or garden you have developed a compost producing pit. If that fails, macrophages will move in to consume the affected cell or other cells will attempt to deny nutrition to the affected cell. Hydrocarbons are compounds that contain carbon and hydrogen in them. Many carcinogens that could make their way into the body actually do so in the form of hydrocarbons. (d) Oxides of Carbon If left unchecked, some toxins can lead to irreparable damage and death. Examples include sodium arsenite (Na3AsO3), sodium chlorate (NAClO3). Chapter 1 – Some Basic Concepts of Chemistry. 1. Those that can be degraded by bacteria such as leaves, food wastes are biodegradable and dumped in landfills along with micro-organisms that decompose it. Clean water will have a BOD of below 5 ppm whereas a highly polluted water source will have a BOD of more than 17 ppm. This results in a heating effect upon the earth thus increasing the earth’s temperature. Without greenhouse gases, the earth’s average temperature will decline thus making this planet uninhabitable. Smog is a combination of smoke and fog which causes air pollution. Acid rain when reacting with limestone causes loss of colour and lustre of monuments, resulting in their disfiguration. How is classical smog different from photochemical smogs? What are the harmful effects of photochemical smog and how can they be controlled? A range of 3–4% of carboxyhemoglobin can decrease the oxygen-carrying capacity of our blood. Hydrocarbons are carcinogenic, i.e., they cause cancer. NCERT Solutions for Class 11 Chemistry Chapter 1 Some basic Concepts of Chemistry. Pests that need to be killed are plant pathogens, weeds, insects, mollusks etc., which affect the plants and lead to their death. Cancer is the result of the failure of all the mechanisms the body has in place to control unchecked cell division. Carcinogenicity and toxicity are not traditionally the same, although one can lead to the other.
