6. Other kinds of monitoring
Besides the above six types of regular monitoring, the Shanghai Environmental Monitoring Center also carries out frequent irregular and variable on-site monitoring, including joint specialized monitoring with environmental agencies in industrial departments. For example, such activities include Investigation on Industrial Pollution Sources of Shanghai undertaken from 1985 to 1987, environmental impact assessment monitoring of large municipal projects - investigation on pollution sources for the comprehensive environmental harnessing of the Suzhou River, and comparative monitoring on air quality and traffic noise before and after the Inner Ring Road and the North-South Viaduct were built. Furthermore, monitoring activities supporting the enforcement of environmental laws are also carried out, such as unscheduled monitoring twice a year, on-site monitoring of environmental accidents, monitoring pollution discharge fee collection and monitoring the issuance of pollution discharge licenses.
This irregular monitoring, which is always up-to-date and diligently conducted, provides an important supplement to the regular monitoring, and thus assists the comprehensive environmental harnessing in Shanghai. In 1995, 583,000 items of monitoring data were obtained for quality of air, water, noise, biological and radioactive environment, 460,000 items of data on the investigation of pollution sources were collected, among which 380,000 were for waste water and 80,000 for industrial furnaces and kilns. 5 per cent of the boilers in all the ‘Zones with Smoke-and--dust under Control’ were rechecked and monitored. The monitoring of boilers in the major power plants, the by-road monitoring of automobile exhaust gas and the spot-checks on motor works and main vehicle users were all accomplished as scheduled, 14,000 items of basic data were collected.
