TCP has a low toxicity potential for terrestrial micro-organisms
Walton et al (1989) investigated the effect of a nominal
concentration of 1000 µg TCP/kg soil upon the microbial activity in two
different soils (silty and sandy loam) by measuring soil respiration as
an indicator for microbial activity. TCP exhibited 7.74 and 17%
reduction compared to the control, which suggests a 4-day EC10
and 4-day EC25 of < 1 g/kg soil dw for
Captina silt loam and McLaurin sandy loam respectively. In both soils
the 6-day EC0 was < 1 g/kg soil dw.
In conclusion these results indicate a low toxicity potential of
TCP for terrestrial micro-organisms.
