Mike Iacchetta
Mike Iacchetta is a Biologist at the Columbia Environmental Research Center.
Mike joined CERC in March 2020 as a Biologist in the Restoration Ecology Section of the Ecology Branch. His work focuses on ecotoxicology and the biological effects of contaminants to aquatic and terrestrial organisms. He works closely with the USGS Environmental Health Program and other partners to understand the effects of contaminant exposure and other stressors to biota. Previous to his time with USGS, Mike has worked for several institutions across the United States studying the behavioral, physiological, and biological responses of amphibian and reptile populations to environmental stressors.

Chemical and biological data from chronic bioassays with native Spea multiplicata exposed to field-collected water or sediment from the Pinyon Plain Mine containment pond in Arizona, USA, or single metals in water-only tests Chemical and biological data from chronic bioassays with native Spea multiplicata exposed to field-collected water or sediment from the Pinyon Plain Mine containment pond in Arizona, USA, or single metals in water-only tests
The dataset reports biological endpoints (survival, growth, developmental stage, and body burden of selected metals) for larval spadefoot toads (Spea multiplicata) in laboratory-based exposures to 1) field-collected water or sediment from a containment pond at the Pinyon Plain Mine in Arizona, USA, during its pre-production phase and 2) six concentrations of copper or cobalt in water...
Acute toxicity of nine critical elements to Hyalella azteca, Lampsilis siliquoidea, Lymnaea stagnalis, Neocloeon triangulifer, and Pimephales promelas with bioaccumulation data of three elements in Lymnaea stagnalis Acute toxicity of nine critical elements to Hyalella azteca, Lampsilis siliquoidea, Lymnaea stagnalis, Neocloeon triangulifer, and Pimephales promelas with bioaccumulation data of three elements in Lymnaea stagnalis
We conducted nineteen acute toxicity assays to address knowledge gaps associated with nine critical elements: cerium (Ce), cobalt (Co), indium (In), lanthanum (La), lithium (Li), neodymium (Nd), osmium (Os), platinum (Pt), and praseodymium (Pr). Acute aquatic exposures of these elements were conducted with five organisms: an amphipod (Hyalella azteca), a mussel (Lampsilis siliquoidea), a...
Survival, neonate counts, and water quality measurements in controlled exposures to long-term wildland fire retardants to Ceriodaphnia dubia Survival, neonate counts, and water quality measurements in controlled exposures to long-term wildland fire retardants to Ceriodaphnia dubia
We investigated the survival and reproductive success of Ceriodaphnia dubia that were exposed to a concentration series of four current-use fire retardants (Phos-Chek 259-Fx Phos-Chek MVP-Fx, Phos-Chek LC95A-Fx, and Phos-Chek LC95A-R) to determine if exposure duration and concentration of the product altered the survival of C. dubia and the number of neonates produced by C. dubia. We...
Buffalo and Silver Carp individual and survival data following surgery using the sedation methods at Columbia Environmental Research Center, Columbia, Missouri, USA from 2022 to 2023 Buffalo and Silver Carp individual and survival data following surgery using the sedation methods at Columbia Environmental Research Center, Columbia, Missouri, USA from 2022 to 2023
The dataset includes capture and individual data for silver carp and buffalo from 2022 and 2023. Fish were captured in the Missouri River and tributaries and transported to the Columbia Environmental Research Center, Columbia, MO, USA. Fish were assigned to one of four treatments to examine different sedation techniques for surgical implantation of artificial transmitters: tricaine
Water chemistry and biological data of Rainbow Trout following aquatic exposure to weathered wildland fire retardants after application to substrate Water chemistry and biological data of Rainbow Trout following aquatic exposure to weathered wildland fire retardants after application to substrate
We investigated whether the length of time fire chemical weathers on a terrestrial substrate before mixing into aquatic environments alters the chemical’s toxicity when encountered by juvenile rainbow trout. We also looked at whether the type of substrate where the chemical is applied affects its toxicity to juvenile rainbow trout after mixing into water. Two fire chemicals (Phos Chek...
Chemical and biological data from acute toxicity tests with road dust suppressant chemicals and five freshwater organisms Chemical and biological data from acute toxicity tests with road dust suppressant chemicals and five freshwater organisms
Dust suppressants and soil stabilizer products are applied to unpaved roads worldwide to reduce dust production and stabilize road surfaces. Although these products may enter roadside surface water through runoff or leaching, little information is available on environmental fate or aquatic toxicity. The data reported here include the acute toxicity of 27 dust suppressant/soil stabilizer...
Long-term surgery survival, body condition effects, and incision healing of Silver Carp and buffalo species comparing sedation methods across seasons Long-term surgery survival, body condition effects, and incision healing of Silver Carp and buffalo species comparing sedation methods across seasons
Objective Internal tagging for telemetry studies requires invasive surgery procedures, necessitating sufficient sedation to support animal welfare. Challenges with existing chemical sedatives have resulted in technological alternatives, including electrosedation, with these newer methods less extensively studied. Our primary objective was to understand long-term survival, body-condition...

Environmental persistence and toxicity of weathered wildland fire retardants to rainbow trout Environmental persistence and toxicity of weathered wildland fire retardants to rainbow trout
Long-term fire retardants are employed to combat and control wildfires by altering the way fuels burn, and they continue to decrease fire intensity after water in the retardant solution has evaporated. After application, fire retardants may persist on dry stream beds or in riparian habitats before precipitation events flush the retardant into intermittent streams. We exposed juvenile (30...

A multidisciplinary approach that considers occurrence, geochemistry, bioavailability, and toxicity to prioritize critical minerals for environmental research A multidisciplinary approach that considers occurrence, geochemistry, bioavailability, and toxicity to prioritize critical minerals for environmental research
Critical minerals (or critical elements) are minerals or elements that are essential to global security and development and have supply chains vulnerable to disruption. In general, knowledge of the environmental behavior and health effects of critical elements is needed to support the development of safe and environmentally responsible supplies. This knowledge includes identifying...

Toxicity of wildland fire retardants to rainbow trout in short exposures Toxicity of wildland fire retardants to rainbow trout in short exposures
Long-term wildland fire retardants are one important tool used to control and suppress wildfires. During suppression activities, these retardants may enter waterbodies; thus, there is a need to understand their potential effects to aquatic biota. We investigated the effect of three current-use wildland fire retardants to juvenile rainbow trout (Oncorhynchus mykiss) survival in short...

Toxicity of wildland fire-fighting chemicals in pulsed exposures to rainbow trout and fathead minnows Toxicity of wildland fire-fighting chemicals in pulsed exposures to rainbow trout and fathead minnows
Intrusions of fire-fighting chemicals in streams can result from containment and suppression of wildfires and may be harmful to native biota. We investigated the toxicity of seven current-use fire-fighting chemicals to juvenile rainbow trout (Oncorhynchus mykiss) and fathead minnows (Pimephales promelas) by simulating chemical intrusions under variable field conditions to provide insight...
