“…This problem is especially daunting for transportation planners who seek to increase mobility by expanding marine transportation options. [1][2][3][4][5] The problem is complex, because marine transportation can take many forms. In terms of passenger transport, ferry services are growing in the United States, particularly in urban coastal waters.…”

“…Similar studies conducted on source identification at various places of Mumbai region also indicated crustal matter and sea salt as the main sources contributing to particulate pollution along with other sources such as oil combustion, road dust, metal industries and coal combustion (Sharma and Patil, 1994;Kumar et al, 2001). Similarly, soil, road dust, vehicular emissions and coal combustion were proved to be the potential contributing sources of atmospheric particulate matter load in other parts of India (Gupta et al, 2008;Kulshrestha et al, 2009;Tiwari et al, 2009;Khare and Baruah, 2010;Shridhar et al, 2010). Around 42% of the total variance was explained by the soil derived source in the coarse fraction and about 39% variance was explained in the fine fraction.…”

The goal of the study is to investigate elemental concentrations and source signatures of particulate matter at a selected receptor site in an urban area Navi Mumbai which is one of the hot spots of India with heavy industrialization. To achieve the objective, particulate matter samples were collected from 2008-2010 using Gent sampler with the automatic dichotomous size segregation unit. It was observed that the three year average concentrations of coarse ((PM 10-2.5µm ) and fine (PM 2.5µm ) fractions of PM were 89.92 (µg m -3 ) and 42.25 (µg m -3 ) respectively which were higher than the national standards prescribed by Central Pollution Control Board (CPCB), India. Subsequent elemental analysis of air filters using INAA and EDXRF showed marginally higher levels of anthropogenic derived elements. Furthermore, in the present study potentially contributing sources of coarse and fine PM were identified using two different receptor model techniques Factor Analysis (FA) and Positive Matrix Factorization (PMF). Six possible contributing sources of coarse fraction and seven probable sources of fine PM were identified by both the techniques. Further, sources identified by the receptor techniques and the comparability between the two techniques were also evaluated.

Abstract. This paper represents, for the first time, scientific data as a part of monitoring air quality in the city of Split. The city has a problem with the air pollution mostly caused by anthropogenic activities and partly by natural origin activities. This study presents results of monthly and seasonal variations of NO 2 , SO 2 and black-smoke as well as the influence of meteorological parameters on observed concentration levels. Average seasonal values for SO 2 ranged from 22.54 to 54.81 g m -3 , for NO 2 from 48.24 to 56.38 g m -3 and for black-smoke from 4.15 to 5.64 g m -3 . The results obtained for SO 2 and black-smoke were below, while for NO 2 were above the limit value of pollutants in the air recommended by Croatian Government (Air Protection Act (OG 178/04); Regulation on limit values of pollutants in air (OG 133/05)).As the result of stable meteorological conditions (high temperatures and drought), the increase in SO 2 concentration was significant in summer period, while the concentrations of NO 2 and black-smoke were not significantly changed during year and did not depend on other parameters.
