Intra- and interspecific toxicity testing methods and data for nematodes exposed to metals

Twenty-four hour median lethal concentration (LC50) toxicity tests were performed with five species of nematodes (Caenorhabditis elegans, Caenorhabditis briggsae, Pristionchus pacificus, Oscheius tipulae, and Oscheius myriophila) in response to copper chloride and zinc chloride. In addition, lethality tests were also performed with seven strains of C. elegans (N2 > 1 year in culture, N2 newly acquired, N2 ancestral, ED3053, JU258, JU1171, and MY1) exposed to copper chloride. Nominal chemical concentrations were validated and analyzed according to U.S. Environmental Protection Agency method 6010 using inductively coupled plasma-atomic emission spectroscopy (ICP-AES). This paper combines the datasets previously published separately by Heaton et al. (2020, 2022). The goal is to catalog all raw and analyzed toxicity data collected from both studies in a single consistent information source for use by the scientific community.
