Formerly an agricultural- and fisheries-based province, Samut Sakhon in 2020 has more than 6,000 factories, most of them small, employing fewer than 50 workers, and too small to warrant much attention from Thailand's Pollution Control Department (PCD). Small firms lack the budgets to install the environmental gear that would help protect the environment.

Soil and water samples from the industrial area of Mueang District were found to be contaminated with high levels of arsenic, lead, cadmium, chromium, zinc, copper, and nickel. High levels of [[persistent organic pollutants]] (POPS), byproducts of industrial processes, were present in eggs from free-range chickens. An egg tested by researchers was found to have 84 [[nanogram]]s per kilogram of [[dioxin]]s and [[furan]]s, a level 33 times higher than the safety limit observed by the European Union.<ref name="BP-20200209" />

Samut Sakhon (Thai: สมุทรสาคร, pronounced [sā.mùt sǎː.kʰɔ̄ːn]) is one of the central provinces (changwat) of Thailand, located along the coast of the Gulf of Thailand. In 2019, it had a population of 584,703,[5] and an area of 872 km²,[6] making it the 33rd most populated province whilst being the 4th smallest. Neighboring provinces are (from the southwest clockwise) Samut Songkhram, Ratchaburi, Nakhon Pathom, and Bangkok. Samut Sakhon is part of the Bangkok Metropolitan Region.

Toponymy

The word samut originates from the Sanskrit word samudra meaning 'ocean', and the word sakhon from Sanskrit sagara meaning 'lake'.

Geography

Samut Sakhon is at the mouth of the Tha Chin Klong River, a distributary of the Chao Phraya River, to the Gulf of Thailand. At the coast are many salt pans used for harvesting sea salt.[6] The total forest area is 42 km2 (16 sq mi) or 4.9 percent of provincial area.[5]

Climate

Samut Sakhon province has a tropical savanna climate (Köppen climate classification category Aw). Winters are dry and warm. Temperatures rise until May. The monsoon season runs from May through October, with heavy rain and somewhat cooler temperatures during the day, although nights remain warm. Climatological data for the period 1981–2010: Maximum temperature is 39.7 °C (103.5 °F) in April and May and the lowest temperature is 12.0 °C (53.6 °F) in December. The highest average temperature is 35.4 °C (95.7 °F) in April and the minimum average temperature is 22.0 °C (71.6 °F) in December. Mean annual rainfall is 1648 millimeters. The maximum daily rainfall is 248 millimeters in May. Mean rainy days average 130 days per year.[7]

History

The oldest name of the area is Tha Chin ('Chinese pier'), probably referring to the fact that it was a trading port where Chinese junks arrived.[8] In 1548 the city Sakhon Buri was established, and was renamed Mahachai in 1704 after the Khlong Mahachai which was dug then and connected with the Tha Chin River near the town. King Mongkut gave it its current name, but the old name Mahachai is still sometimes used by locals.[9]

It was established by the Act Establishing Changwat Samut Prakan, Changwat Nonthaburi, Changwat Samut Sakhon, and Changwat Nakhon Nayok, Buddhist Era 2489 (1946), which came into force on 9 May 1946.[10]

Economy and environment

Formerly an agricultural- and fisheries-based province, Samut Sakhon in 2020 has more than 6,000 factories, most of them small, employing fewer than 50 workers, and too small to warrant much attention from Thailand's Pollution Control Department (PCD). Small firms lack the budgets to install the environmental gear that would help protect the environment. As a result, Samut Sakhon is one of the most polluted provinces in the nation.[11]

Soil and water samples from the industrial area of Mueang District were found to be contaminated with high levels of arsenic, lead, cadmium, chromium, zinc, copper, and nickel. High levels of persistent organic pollutants (POPS), byproducts of industrial processes, were present in eggs from free-range chickens. An egg tested by researchers was found to have 84 nanograms per kilogram of dioxins and furans, a level 33 times higher than the safety limit observed by the European Union.[11]

The most polluted air in Thailand in 2018 was found to be in Samut Sakhon province.[12] According to the PCD, the level of PM2.5 in the provincial atmosphere in 2019 was unusually high, measuring as high as 195 micrograms per cubic metre (μg/m3). During the air pollution "season" of 2018–2019, PM2.5 levels exceeded the PCD's safe threshold of 50 μg/m3 for 41 days.[11]

Samut Sakhon is a leading sea salt producer. According to a survey in 2011, 12,572 rai of salt pans were managed by 242 families in Samut Sakhon.[13]

Health

Samut Sakhon Hospital is the main hospital of Samut Sakhon province, operated by the Ministry of Public Health. The ministry also operates a general hospital, Krathum Baen Hospital in Krathum Baen district.

Ban Phaeo is served by Ban Phaeo General Hospital, the only hospital public organisation in Thailand.

Transportation

Samut Sakhon is along the Maeklong Railway, operated by the State Railway of Thailand and is served by Mahachai railway station on the east bank of the Tha Chin River and Ban Laem railway station on the west bank.

Symbols

Brand

The provincial seal shows a Chinese junk in front of the coast, with a factory and a smoking chimney in the background. Both refer to the old trading tradition as well as the local industries.

The provincial flag is horizontally divided pink/light blue/pink (1:3:1) the provincial seal in the middle.

The provincial brand is a picture of a white factory, a fishing boat, a fish and blue water and a green leaf.

The provincial tree is commonly called blackboard tree or devil's tree (Alstonia scholaris).

The provincial aquatic animal is the short mackerel (Rastrelliger brachysoma) what with Samut Sakhon is the first province to have short mackerel fishing and has the largest amount of this species of fish caught in Thailand.

The provincial slogan is "Fishing city, factory town, agricultural ground, historic site".[14]
