“…The average concentration of particulate matter in the diesel engine compartment is 1500μg/m 3 , and the particle size distribution is in the range of 0.5-202μm. The chemical forms of elemental carbon (EC), organic carbon (OC) and total carbon (TC) of the particulate matter are determined [11].…”

The purpose of this study is to study the air contaminants in the cabins of underwater vehicle. The basic data help for the better research of the underwater vehicle cabin environment standard and the control strategy. Pretreatment and analysis method of volatile organic compounds was preconcentration combined with gas chromatography under the condition of liquid nitrogen and detected by chromatography-mass spectrometry. The pollution of particles, carbon monoxide and carbon dioxide during the underwater vehicle voyage were monitored by online monitoring instrument. Altogether 34 kinds of pollution components were detected, most of which were low in concentration. Some are low olfactory threshold or high toxic components, such as dimethyldisulfide, benzene, carbon disulfide, trichloromethane, and several reached to ppm level. The contamination of the particles was mainly fine particles and part cabins exceeded the national standard of indoor air quality. The highest concentration of carbon dioxide in accommodation space exceeded the permissible concentration of atmosphere composition aboard diesel underwater vehicle compartments. The increase submerged time made the environment in the cabins deteriorate. The concentration of trace contaminants may close to or beyond the relevant standards with the prolonged time. The volatile organic compounds, particles, carbon monoxide and carbon dioxide aggravated the air circumstance in the cabins. It should be determined the permissible concentration of air contaminants in underwater vehicle as soon as possible.

“…The health hazards of diesel particulate matters (DPM) are well known and a concentration of about 200 µg m -3 at short exposure period of 2 hrs can lead to airway inflammatory response (Nigthtingale et al, 2000;Behndig et al, 2006). Most of the DPM consists of elemental carbon core of 0.01-0.08 µm in diameter (Gan et al, 2010). As a result of these health concerns, several authorities have set exposure standards or guidelines for DPM.…”

This study examined the toxicity potential of total suspended particulate in the airshed of a haulage vehicle park located in a major highway connecting Lagos, the commercial centre of Nigeria to its other parts. It has an approximate area of 0.6 km 2 . Ambient air total suspended particulates (TSP) were monitored at five different sub-parks using the GT331 particulate monitor. A control sampling point was also set at about a kilometer southward of the sub-parks. The average measured particulate concentrations within the park ranged between 197.07 and 653.28 µg m
