It is a 242 page book which is seemingly not available in e book form or even in print form in libraries. Only came up in 4 results in Google.

I would like to see their findings. I'll keep "googling" to see if anyone else has some readily available research.

I've been moaning about sunscreens to every marine biologist I've met - even here ...

But it's only now, several years later some (too few) scientists are bothering to look into this potential pollution problem.

The reality is probably that sunscreens are as bad for humans as for sea-life.

Could be the seaweed that’s to blame:

Can sea urchins survive giant seaweed invasion?

heres another tragedy:


"..It was just a few weeks ago that 50,000 bees were found dead in an Oregon parking lot, and now the ongoing problem has hit north of the border in Ontario, Canada where more than 37 million bees have been found dead.

.In the past, many scientists have struggled to find the exact cause of the massive die-offs, a phenomenon they refer to as “colony collapse disorder” (CCD). In the United States, for seven consecutive years, honeybees are in terminal decline.

The problem has brought beekeepers to crisis in an industry responsible for producing apples, broccoli, watermelon, onions, cherries and a hundred other fruits and vegetables. Commercial honeybee operations pollinate crops that make up one out of every three bites of food on our tables.

According to the annual survey by the Apiary Inspectors of America and the US government’s Agricultural Research Service (ARS),
The number of managed honeybee colonies has fallen by over 30%..."

Pesticides killed the bees:

Woah!

Am a little concerned to read this on sea-urchin habitats ...

Status: Very vulnerable habitat to the dredging and trawling, and brine from
desalination plants.

Desalination plants are the major new development (last 5 years) in this area.

Echinoderms are osmoconformer organisms and are expected to be very sensitive to brine
discharges.
The objective of this study is to examine the use of echinoderms as early warning
indicators of the impact of brine discharges and its application in the management of desalination
discharges. We sampled using visual census along transect lines, for nine consecutive
years and in three different stations, i.e. before the seawater reverse osmosis desalination
plant began operating and thereafter. One year after the plant operation, echinoderms disappeared
from the localities affected by the desalination brine.
When the desalination brine
was diluted with seawater prior to discharge, it was observed a recovery of echinoderm densities
in these localities. Therefore, echinoderm populations may be used as early indicators
to monitor impacts associated with a desalination brine discharge, but also to detect a possible
recovery of a previously impacted area when additional mitigation measures to reduce
the impact of brine discharge have been implemented.

Is the nearest desalination plant to the Paphos coastline the one in Kouklia?

Has it been set up to produce fresh water for the golf-courses at Secret Valley?

President of Cyprus announce Paphos desalination plant operation

Despite the fact that it has been in operation since last November, the President of the Republic of Cyprus held a formal unveiling last week of a 30,000 m3/d (8 MGD) SWRO plant at the village of Kouklia in southwest Cyprus’ Paphos District. According to Andreas Manoli of Cyprus’ Water Development Department, Italy’s Protecno constructed the plant under an EPC contract. The four-train plant is fitted with ERI PX energy recovery devices, DOW membranes and BEL pressure vessels.
