entomotoxicology alternative matrices forensic toxicology

In addition, there are several studies that use this matrix for the analysis of drugs of abuse for clinical and forensic purposes, such as cannabinoids [28, 29], amphetamines [30, 31], cocaine [32, 33], opioids [34, 35], and benzodiazepines [36]. Because meconium begins to form around 1112th week of gestation (when a fetus beginsswallowing amniotic fluid) and accumulates thereafter until birth [102, 105], it has been used as alternative matrix for assessing prenatal exposure to drugs (theoretically along the second and third trimesters of pregnancy) [102, 106, 107]. This study was financed in part by the Coordenao de Aperfeioamento de Pessoal de Nvel SuperiorBrasil (CAPES)Finance Code 001 (Fellowships and Grant Pr-Forenses n.25/2014) and Grant #2017/18021-5, 2013/19653-4 and 2017/10387-0, So Paulo Research Foundation (FAPESP).

Forensic entomotoxicology studies the usefulness of insects as alternative toxicological samples. For example, in a study by Harper [157], postmortem blood and VH were collected from 51 decedents and microbiological analyses revealed no significant amounts of bacteria or fungi in VH and high diversity of microorganisms in 32 postmortem blood specimens. Forensic Entomology is the one of the part of forensic science where we get information about insects which helps in the investigation legal case relating to both human and animals, with the help of arthropods.

Forensic Entomotoxicology is the branch of forensic science in the use of collecting and investigating insect and toxicology evidence.

As a potential perspective inforensic toxicology, the topic of alternative matrices will be continuously explored, especially emphasizing NPS.
