On-site testing of air emissions which involves samples collection and on-site measurements from general environment (ambient) and on-site noise measurements with optional data-logging services.

The Philippines has established an air ambient monitoring program to continuously monitor the quality of air in the country. The program is implemented by the Department of Environment and Natural Resources (DENR) through its Environmental Management Bureau (EMB). The objective of the program is to provide timely and accurate information on the state of air quality in different regions of the country to help protect public health and the environment.

Under the air ambient monitoring program, the DENR-EMB operates monitoring stations across the country to collect data on air quality. The stations use specialized equipment to measure the concentrations of various pollutants in the air, such as particulate matter, sulfur dioxide, nitrogen dioxide, and ozone. The data collected from the monitoring stations is analyzed and used to generate air quality indices that provide information on the current state of air quality in the region.

The air ambient monitoring program in the Philippines has helped to raise public awareness about the importance of air quality and has provided valuable information to policymakers to develop strategies to mitigate air pollution. The program has also helped to identify areas where air quality is poor, leading to targeted interventions to reduce pollution levels and protect public health and the environment. Overall, the air ambient monitoring program in the Philippines is an important tool in the country's efforts to ensure clean air for its citizens.
