Biodegradable EDDS ([S,S]-ethylenediaminedisuccinic acid) is an emerging chelant for enhancing heavy metal extraction. During soil remediation that involves continuous flushing, extraction often limited by the amount of EDDS. Under deficiency, initial Zn and Pb followed resorption was observed in batch kinetic experiments. Speciation calculations indicated percentages ZnEDDS2− PbEDDS2− respective dissolved concentrations decreased with time, whereas contribution CuEDDS2− to total increased...

In this paper, waste management in Alberta (AB) and British Columbia (BC) from 1996 to 2010 are examined with respect generation characteristics efficiency. The daily average rates AB BC were 3.34 kg/capita 2.50 kg/capita, respectively. It was found that annual family income has a positive relation residential both provinces, as did the proportion of educated citizens. Gross domestic product positively related non-residential AB, negatively BC. Annual agricultural farm cash receipts AB’s...
