Which body fluids are used to test for the presence of chemicals such as elicit drugs and poisons by forensic toxicologists? (choose all that apply)

Blood, urine and saliva.

Explanation:

A forensic toxicologist refers to a professional or an expert who is a certified investigator in determining and identifying the presence of hard drugs or poisons in the body by scientifically testing bodily fluids and tissues.

This ultimately implies that, forensic toxicologists are certified professionals (investigators) who are saddled with the responsibility of collecting evidence e.g presence of alcohol, hard drugs, or poisons, after an unfortunate incident such as murder has occurred. This is to determine whether or not the evidence collected at the crime scene, from the victim or suspect are connected to the crime.

Hence, the body fluids which are used to test for the presence of chemicals such as elicit drugs and poisons by forensic toxicologists includes;

I. Blood.

II. Urine.

III. Saliva.

a fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing energy originating in ancient photosynthesis.[1] the age of the organisms and their resulting fossil fuels is typically millions of years, and sometimes exceeds 650 million years.[2] fossil fuels contain high percentages of carbon and include petroleum, coal, and natural gas.[3] other commonly used derivatives include kerosene and propane. fossil fuels range from volatile materials with low carbon to hydrogen ratios like methane, to liquids like petroleum, to nonvolatile materials composed of almost pure carbon, like anthracite coal. methane can be found in hydrocarbon fields either alone, associated with oil, or in the form of methane clathrates.

the theory that fossil fuels formed from the fossilized remains of dead plants by exposure to heat and pressure in the earth's crust over millions of years was first introduced by andreas libavius "in his 1597 alchemia [alchymia]" and later by mikhail lomonosov "as early as 1757 and certainly by 1763".[4] the first use of the term "fossil fuel" was by the german chemist caspar neumann, in english translation in 1759.[5]

in 2017 the world's primary energy sources consisted of petroleum (34%), coal (28%), natural gas (23%), amounting to an 85% share for fossil fuels in primary energy consumption in the world.[6] non-fossil sources in 2006 included nuclear (8.5%), hydroelectric (6.3%), and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%.[7] world energy consumption was growing at about 2.3% per year. in 2015 about 18% of worldwide consumption was from renewable sources.[8]
