Chemical B. Abiotic C. Biological D. Homeostatic 2. Careers. The results showed that the degradation rate was related positively to the amount of inoculation, when the dose was increased to 0.6 mg x kg(-1), total petroleum hydrocarbon (TPH) degradation rate was 87% in 48 days. A. Bioremediation represents an environmentally sustainable and cost effective technology, improving microbial degradation of organic pollutants. Another factor may be the increased salinity of the upper intertidal and supratidal zones because these parts of the beach are potentially subject to prolonged evaporation and only intermittent inundation. Compared to the South, the North had colder winters, shorter summers. The soil samples were taken from the site of a former oil products depot from an industrial area (Romania). 21806100), Natural Science Foundation of Shanghai (No.18ZR1414100). a 15) Biochemical oxygen demand is a measure of the A) number of bacteria present in a water sample. The soil samples taken were analyzed from a physical and chemical point of view: texture, pH, soil micronutrient content, metals concentration and petroleum hydrocarbon concentration (PHCs). The degradation mechanism was studied by analyzing soil microbial community and functional genes through metagenomics during the degradation process. EX: microbes degrade human-made chemicals to obtain energy. As we know that PH-contaminated soil affects human health directly, such as (i) contact with soil, (ii) via inhalation of vaporized contaminants, and (iii) infiltration of soil contamination into groundwater aquifers used for human consumption. Numerous factors are known to affect both the rate and the extent of hydrocarbon biodegradation in contaminated soils. Answer: (c) 2. B) amount of oxygen present in a water sample.
