Trace gas emissions from husbandry by combining satellite airborne and surface observations
Animal husbandry produces the potent greenhouse gas, methane, which traps heat in the atmosphere (like carbon dioxide). This industry also produces ammonia, which leads to particle (smog) formation that’s dangerous when breathed and affects sunlight and thus
The destruction of endocrine disruptors in wastewater
In Canada, endocrine disruptors are a very topical issue in wastewater effluent quality. We define endocrine disruptors as chemicals that can interfere with the endocrine or hormone systems in wildlife and humans. Results can vary from different
