  Environmental chemistry  Environmental is the scientific study of the biochemical and chemical phenomena that occur in natural places.  It is a study that is more than air, water, soil, and CHEMICALS.  This field uses various techniques of genetics, biology, maths, hydrology, etc. Environmental chemists are responsible for finding how the unpolluted environment functions and finding ways of sustainable development that do not harm the environment. It also contains aspects of analytical chemistry, physical chemistry, organic chemistry, and inorganic chemistry as well as more diverse areas, such as epidemiology, public health, biochemistry, and toxicology. What is environmental chemistry used for? Environmental chemists study how chemicals enter and affect the air, water, and soil. These chemists often focus on issues related to environmental and human health. Many environmental and human health. Many environmental chemists collect water and soil samples from outdoor...

Question 1) What is Good manufacturing practices (GMP)? Answer:   Good manufacturing practices are regulation, codes, and guidelines for the manufacture of drug products, medical devices, in vitro and in vitro diagnostic products, foods. The term “cGMP” is used by the federal government as a current good manufacturing practice. Question 2) What is GLP? Answer:   GLP stands for Good Laboratory Practice. It is a quality control system used in research laboratories to ensure data integrity( i.e. data is generated under high quality and reproducible conditions). enable mutual acceptance of data between countries. Question 3) What are the Rules of lab safety? Answer:   Rule 1:WALK When going into the lab make sure to WALK. there will be no running in the lab. There will be materials and equipment out that can break if you accidentally knock into them. There may be electrical wires on the ground that you may trip over as well. DO NOT RUSH . Walk slowly and be careful.  ...
