Unit: mg/l Analytical monitoring: no<br />

GLP:<br />
no data<br />
Test substance: other TS: commercial grade ammonium sulphate containing <strong>20</strong>.6%<br />
nitrogen.<br />
Remark: Inconsistent information in test methodology described -<br />
between the number of animals per vessel and the total<br />
number of animals used in the test - for a valid testing<br />
regime.<br />
Result:<br />
An LC50 value of 180 ppm was observed at 22.0 °C.<br />
An LC50 value of 60 ppm was observed at 32.5 °C.<br />
Test condition: TEST ORGANISMS: Test organisms were collected from local<br />
ponds and acclimated to laboratory conditions for 10 to 96<br />
hours.<br />
TEST VESSEL: 500 ml glass beakers containing unchlorinated<br />
borehole water (pH 7.5; DO 7.6 ppm; total alkalinity 190 ppm<br />
as CaCO3; ammonia nitrogen 0.05ppm).<br />
TEST METHODOLOGY: Twenty animals were kept per vessel, and<br />
four replicates of each test were conducted, along with<br />
controls. Bioassays were conducted after the method of APHA,<br />
AWWA, and WPCF (1971): Standard method for the examination<br />
of water and wastewater, 13th Ed. APHA Inc, New York, 874.<br />
96 hour tests were carried out for insects and molluscs.<br />
Test temperatures were 22.0 + 1.1 °C and 32.5 + 1.3 °C. 1150<br />
organisms were used in this test, a similar test using<br />
another substance, and the controls. The LC50 and LC 95<br />
values were determined by probit analysis.<br />
Reliability: (4) not assignable<br />
Documentation insufficient for assessment. pH not measured.<br />
Ammonium sulfate fertiliser characterisation is very<br />
limited. Concentrations not measured. Number of<br />
concentrations used and nominal concentration values not<br />
stated.Limited documentation of results.<br />
