− | <br> | + | <br>The previous VAST challenge identified chlorodinine as one of the toxic chemical contaminants produced by factories in the preserve. From 2014-2016, levels of chlorodinine were constant across all stations but then abruptly fell from 2016-2017. One possible reason for this sudden decline is the introduction of environmental regulations in the preserve. However, on 23 June 2016, there was a spike in chlorodinine readings at Kohsoom, the closest station to the location of waste dumping. It is possible that the waste dumping occurred that day and is worth an investigation. |

While there has not been high levels of cyanide detected in areas close to the location of the waste dumping, significantly high readings of cyanide were detected in Decha, in 2010 and 2012. Investigations should be carried out in any industrial sites near the area as these sensor readings are a cause for concern. |

Wildlife Concern
To investigate the impact on the Pipit and wildlife, the data visualization will focus on chemicals that are toxic to living organisms.
Concerns | Visualization |
---|---|
1. Arsenic
Arsenic is a heavy metal that is known to be extremely toxic to living organisms. It is therefore worrying that Arsenic readings are prevalent across the preserve since 2008, with particularly high readings in Tansanee in 2015. |
|
2. Cyanides
Cyanide is also known to be toxic to living organisms. However, sensor readings of cyanide are not comprehensive. Small levels of cyanide are detected from 2008 across several stations but the readings stop in 2010. From 2010 to 2012, cyanide readings are present in Decha with worryingly high levels in 2010 and 2012. |
|
3. Mercury
Mercury is toxic to living organisms. Since 2008 there have been detection of mercury across several stations in the preserve, with Achara having the highest levels in 2010 and 2011, and Kohsoom (the station nearest to the waste dumping site) also having high levels from 2010 to 2013. However, there are no longer any sensor readings at Kohsoom from the middle of 2013 so the status of mercury levels there in recent times is unclear. |
|
4. Methylosmolene
This toxic manufacturing chemical contaminant has been detected since 2014 but it is unclear if it has existed in the preserve before then. Low levels of it occur is most parts of the preserve but sensor readings has increased significantly in Kohsoom starting from mid 2015 to 2016. However, sensor readings are patchy. For example, readings are missing from November and December 2015. |
|
5. Petroleum Hydrocarbons
Excessive petroleum hydrocarbons in groundwater would be toxic to wildlife in the preserve. From 2008 it has been present at low levels across the preserve. However, in 2012 readings were higher than usual, though the data is very patchy. An unusually high reading was also detected at Somchair in September 2009. |
|
6. Water temperature
Maintaining a constant water temperature is essential to living organisms that live in water. From 2008, the water temperature fluctuation has been regular, except for a significantly high temperature on 15 August 2016 at Tansanee. |
