Terrestrial toxicity of n-heptanoic acid was assessed on microbial
populations (OECD 216 nitrification assay), earthworms (OECD 222
reproduction assay) and six species of plants representing a large area
of the plant phylogenetical distribution (OECD 208 seedling emergence
and growth assay). Microbes were the less sensitive trophic level with
inhibition of nitrification occurring above 300 mg heptanoic acid per kg
soil dw. Plant sensitivity was very species dependent, with NOEC/EC10
ranging from 1.2 mg/kg soil dw to above the highest tested concentration
(100 mg/kg soil dw). Heptanoic acid mainly affected plant growth, as no
effect was observed on emergence. No sign of phytotoxicity was observed
in any treatment. Earthworms were less sensitive than the most sensitive
plant, with a reproductive NOEC of 10 mg/kg soil dw.
