“…Substantial amounts of Cd are present in tissues and contents of the gastrointestinal tract. Despite representing a significant proportion of body mass, muscles contain a relatively small portion of the total body Cd (Gašparík et al, 2017;McAuley et al, 2018;Barrasso et al, 2018).…”

Background: A closer relationship has been established between entomology and toxicology, giving rise to a new field known as entomotoxicology, which focuses on the bioaccumulation of toxic substances in scavenging insects and other arthropods. Methods: This study investigates the impact of lethal doses of Mercury Chloride (HgCl2) and Cadmium Chloride (CdCl2) administered to male rabbits (Oryctolagus cuniculus Linnaeus) on the distribution of Mercury and Cadmium in rabbit organs and their subsequent accumulation in Chrysomya albiceps larvae. The experimental groups were subjected to oral administration of specific concentrations of HgCl2 and CdCl2, while a control group received distilled water. Organ dissection and subsequent larval feeding were followed by acid digestion for sample preparation and inductively coupled plasma torch spectrometry coupled with a mass spectrometer (ICP-MS) was employed for analysis. Result: Results indicate a significant increase in Mercury concentrations in treated rabbit organs, with the liver exhibiting the highest concentration. Cadmium showed diverse distribution among rabbit organs, with the highest concentrations in the kidneys. Ch. albiceps larvae, reared on rabbit organs, exhibited varied concentrations of both Mercury and Cadmium, with significantly higher levels in the treated group. These findings underscore the ecological implications of heavy metal exposure and the potential utility of insect larvae in forensic investigations as bioindicators of environmental contamination.

Indigenous peoples in Canada are disproportionately exposed to environmental contaminants and may face elevated health risks related to their unique cultural, spiritual, and economic relationships with the land, including the use of traditional food systems. However, to date, institutionalized approaches to assess risks to human and ecological health from contaminants have not been well developed or implemented with Indigenous community contexts in mind. There is regulatory interest in developing new approach methods for risk assessment, and thus an opportunity to increase their relevance to Indigenous communities in which they will be ultimately applied. Therefore, we conducted an anonymous mixed‐methods survey of those involved with risk assessment in Indigenous communities in Canada to: (1) understand risk assessment practice in Indigenous communities, (2) explore challenges with conventional assessment methods and compare these across sectors, and (3) gather perspectives on the development of new approaches. In all, 38 completed survey responses were received (14% response rate). Respondents were from Indigenous community environment and health offices (21% of respondents), Indigenous governments (8%), federal and provincial governments (21%), and academia (45%). Risk communication was seen as the most challenging part of risk assessment (71% responded “difficult”), and nearly all respondents agreed that time (86%), cost (76%), and resource availability (86%) were “moderate” to “serious” problems. Few respondents (16%) had heard of “new approach methods” for risk assessment, and 76% of respondents (and 100% of community‐based respondents) agreed on the need to develop improved risk assessment approaches. To modernize risk assessment, respondents recommended advancing cumulative risk assessment methods, improving risk communication, and promoting Indigenous leadership and Traditional Knowledge in assessment activities.
