Development and evaluation of RAMP I – a practitioner’s tool for screening of musculoskeletal disorder risk factors in manual handling

RAMP I is a screening tool developed to support practitioners in screening for work-related musculoskeletal disorder risk factors related to manual handling. RAMP I, which is part of the RAMP tool, is based on research-based studies combined with expert group judgments. More than 80 practitioners participated in the development of RAMP I. The tool consists of dichotomous assessment items grouped into seven categories. Acceptable reliability was found for a majority of the assessment items for 15 practitioners who were given 1?h of training. The usability evaluation points to RAMP I being usable for screening for musculoskeletal disorder risk factors, i.e., usable for assessing risks, being usable as a decision base, having clear results and that the time needed for an assessment is acceptable. It is concluded that RAMP I is a usable tool for practitioners.     

中国“达标排放”政策的实证分析及理论探讨

以固定点源烟尘排放为例,从排放标准和监测标准两方面讨论了中国现阶段“达标排放”的状况,指出当前的大气污染源达标排放实际上是“初步达标排放”,现在的排放标准和监测规范合适考核污染源的初步达标排放,不适合考核污染源的连续达标排放。排放标准的规定形式、监测规范和适用范围需要改革。现在的排放标准指标需要与监测规范和超标率限值结合起来,以促进污染源的连续达标排放。

耐镉菌株的分离及其对Cd2+的吸附富集

采用梯度浓度驯化的方法,筛选分离出一株能高度耐镉和富集镉的菌株,初步鉴定为假单胞菌属(Pseudomonas sp.).该菌株在含Cd2+浓度4500mg/L的液体细菌培养基中能够生存,当Cd2+浓度为100mg/L时,pH值为6～8有利于提高菌株耐镉能力.Cd2+为低浓度时菌株积累Cd2+,菌体对Cd2+浓度为100mg/L的积累率达99.1%,冻干菌体对Cd2+的吸附量为8.786mg/g干菌体;当Cd2+浓度大于909mg/L时,菌体表现出外排Cd2+现象.红外分析和电镜观察表明,菌株细胞壁在吸附Cd2+中起重要作用,67.4%的Cd2+吸附在细胞壁上.

Best management practices compliance monitoring approaches for forestry in the eastern United States

Many of the eastern states that have published best management practices (BMPs) or forest management guidelines have also developed compliance monitoring programs to assess the application of these BMPs or guidelines on public and private forest land. The approaches among these states to collecting on-site monitoring data (measuring compliance) and evaluating sites are variable. A survey of eastern states found that almost all southern states monitor application of BMPs, but proportionally fewer of the northern states have established compliance monitoring programs. The state forestry agencies provide the leadership for these programs in most of the eastern states. States that monitor tend to evaluate all public and private forest landowner categories located within their states. In general, northern states monitor a broader array of site resources (e.g., cultural resources, visual quality) as compared to southern states which focus on water quality and wetlands protection. However, northern states focus their monitoring on timber harvesting, forest road construction and maintenance as compared to southern states which tend to monitor a broader array of forest management activities (e.g., site preparation, reforestation). When selecting sites for monitoring, the most common approach is to select some sites from all landowner categories within the state. Many states do not specify any criteria to identify sites for monitoring so that all sites have an equal chance for selection. Some states do use specific criteria to filter sites for monitoring, most commonly size of forest management activity and proximity to water.
