Studies of the local climate of the mid-Holocene in Elk Lake, in North-Central Minnesota show that 7800-6700 yr BP the climate was colder and much drier than today and already between 6700 to 4000 yr BP the mean air temperatures approached the current mean. Those data indicate also that modern "global change" is nothing more than a short episode of warming which has repeatedly occured in the past.

Aflatoxins are highly toxic and carcinogenic mycotoxins found in many foods and feeds. The constant battle of primary producers against these poisons is intentionally left unmentioned by so-called "green" organisations. Besides the many fungicides which are directly aimed at controlling these diseases, several insecticides have an inhibiting effect on production of aflatoxins as well.

Data collected during studies on Lake Ontario indicate that almost all reported measurements for total Cd exceed the recommended limit by at least 5 times. Values for Cu also showed a high percentage of measurements from all regions of the lake greater than the recommended water quality objective. Other metals equalled or exceeded these limits. The concentrations of PCB, dieldrin and other pollutants in Lake Ontario water and fish exceeded the upper limits as well.

The concentration changes of the oceanic fields change with sources, advection and mixing. Detergent and phosphate concentrations in the Atlantic Ocean change with horizontal advection. The detergent map reveals a powerful center of this pollutant south of New York and another significant accumulation north of the Bermuda Islands.

Anabaena circularis is a cyanobacteria found as plankton. Cyanobacteria obtain their energy through photosynthesis and are, therefore, important primary producers of our oceans. As such they can create environmental hazards through algal bloom. On the other hand, their growth can be used as an alternative energy source and their production of cyanotoxins can be biotechnically used for production of anti-HIV agents.

Mast cells protect living tissues against pathogens and are, therefore, ultimately involved in wound healing and immune system defense. Degranulation is the cellular process of releasing antimicrobial cytotoxic molecules by which these and other cells destroy invading microorganisms.
