Benzene Health Issues: Leading & Lagging Indicators

Leading and lagging indicators Health surveillance by conducting a urinary test or blood count can of course show evidence of exposure but these are lagging indicators i.e. after exposure has already taken place by which time damage may have been done. A preferable leading indicator for benzene exposure would be to monitor using a real-time monitoring instrument such as a ...

Bottom–up monitoring of municipal energy and climate policy: more than an alternative to top–down approaches?

Policy evaluation is widely considered important for assessing policies for effectiveness and impact. Municipalities are among the political actors implementing energy and climate policy. Yet, few municipalities have introduced adequate instruments to monitor the effectiveness of their actions. Often, municipal actors consider local greenhouse gas (GHG) inventories to be sufficient to monitor the ...

H&S Operational Efficiency: Plant turnaround

Hazardous chemicals that pose a risk to humans are normally safely transported within the process but obviously during plant turnaround this is no longer the case. As lines and reaction vessels are opened they pose a significant risk of over-exposure, without appropriate control measures. Concentrations can be several hundred (or even thousand) times higher than the occupational exposure ...

Double benefit of monitoring Indoor Air Quality (IAQ)

It is a difficult balance to save money and energy yet maintain a comfortable and healthy indoor air environment. A logical solution to controlling indoor air pollution is good ventilation coupled with IAQ monitoring using gas sensors. This can ensure healthy indoor air as well as a more efficient HVAC system. Typical IAQ investigation and examination consists of taking single-point ...
